We are moving and no longer have a need for a dedicated home theater. This thing is an absolute monster, with tremendous headroom and clarity. I had this driven by an Anthem D1 and driving PSB Platinum M2 right/left and C4 center array, as well as two in-wall PSB 3 way speakers. This amplifier surpasses THX reference volumes easily with absolute clarity. It's a total beast. Weights 86 lbs, mostly from the two giant toroidal transformers in the front, for right and left. Balanced amplifier.

Everything works as it should. Amplifier is in original box and packing, and double boxed.

This is the best amplifier you can buy at this price point.

ATI manufactures amplifiers for some of the well-known EXPENSIVE brands, and they're essentially the same as this one.
